2'0 all whom it may concern-.-

Be it known that I, PATRICK BRALLEY, a citizen of the United States,residing in Oakland, Alameda county, State of California, have inventedan Improvement in Sewing- Machine-Needle Threaders; and Ihereby declarethe following to be a full, clear, and exact description of the same.

My invention relates to a device for threading the needles of sewingmachines.

it consists in certain details of construction which will be more fullyexplained by reference to the accompanying drawings.

Figure 1 is a perspective view of my needle threader in position.showing it turned up and held out of the way after the needle isthreaded. Fig. 3 is an enlarged perspective view of the needle threadingblock. Fig. 4. is a side view of the block, the two parts that form itbeing opened.

The object of my invention is to provide a device which is adjustablewithrelation to the needle and needle bar, so hinged that it may beturned up out of the way when not in use, and readily turned down toclasp the needle, having a hole throughit which exactly coincides withthe eye of the needle, and serves as a guide to direct the threadthroughthe eye, the device being made in two separable parts which will openautomatically by a little pull, to allow the device to be moved away,leaving the needle and thread in position for use.

A is my needle threading block. It consists of two parts fittedaccurately together and having one end secured to a fiat elastic steelplate B which normally holds thetwo parts with their adjacent faceslying together like a single block. Between these two, near the endopposite to the attachment B, is made a tapering hole or countersink Oterminating in a very fine hole upon the opposite side, into which thetapering portion guides the thread. Upon the opposite'side of the blockis a vertical groove or channel D with a spring plate E fixed to oneside and extending over this groove or channel, so that when the deviceis properly adjusted, the needle lies in this groove or channel and isheld in place by the spring E, so that its eye is exactly in line withthe hole 0, and a thread introduced into this hole, will be directedthrough the eye of the Fig. 2 is a sideview' needle. The threadingdevice is then pulled to one side, the thread being held by the hand,and by means of a little groove or channel F extending outward from theside of the hole 0 and between the two pieces A, the thread is enabledto pass between these plates and separate them enough so that when theyare drawn to one side the thread and needle will be left in readinessfor use.

In order to properly adjust the device, I

and this allows a screw I to be passed through the hole in the needlebar, and it extends out through the plate J uponthe front of the arm. Tothis projecting end of the screw is secured the bent arm K slotted toallow the screw to pass through, and having a locking nutL by which itis secured at any desired point.

extends downward and carries the needle threading block A at itsopposite end,sothat when the block A is I disengaged from the needle, itmay be swung upward around the hinge point of the rod and held by aclasp 0. When it is to be used itis turned downward and by springing ita little to'one side, itcan be pushed over the needle so that the needlelies in the vertical channel D and the spring E clasps and holds it inplace as described.

The vertical adjustment of the device is made by means of the screw Iand locking nut L before described, the slotted arm being slipped up ordown until the hole in the threading device is exactly opposite the eyeof the needle. It is then looked firmly by the nut L, and when this isdone, everything is complete and in readiness for use at any time.

The'device being attached to the needle bar, reciprocateswith itandthere is no change in its position relative to the needle. By its use,the finest needle can be easily threaded without difficulty.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-- 1. A threading device for sewing machineneedles consisting of a block having a hole or perforation adapted tocoincide .with the eye of the needle, an arm, to the lower end To thelower arm is hinged a rod or wire M which of which the block is secured,and means for adjustably securing said arm and block to the needle barconsisting of a slotted plate fitted to the arm of the machine andhaving its lower end connected by a hinged joint with the upper end ofthe arm which carries the block, a screw projecting from the needle barthrough a slot in the arm of the machine, and through the slot in saidplate, and a locking nut for adjustably securing said plate, andprovided with means for maintaining the block elevated when not in use.

2. A needle threading device for sewing machines consisting of a blockhaving a hole or perforation adapted to coincide with the eye of theneedle and direct the thread therethrough,an arm carrying the block atits lower end, a slotted plate fitted against the arm of the machinehaving its lower end bent outwardly and hinged to the upper end of thearm which carries the block, about which hinge the device may be turneddown for use and up out of the Way when not in use, a screw pin from theneedle bar passing through a slot in the arm of the machine and throughthe slot in the plate, and a nut engaging said pin and adj ustablysecuring the slotted plate, said nut being provided with a clamp intowhich the block carrying arm may be placed and maintained in an elevatedposition.

3. A device for threading sewing machine needles consisting of a twopart block, a spring plate at one end of the block by which the twoparts are normally held together, a tapered opening or hole madepartially in each block between the meeting faces thereof, a verticalchannel into which the maller part of the hole opens upon the oppositeside, said channel'being adapted to fit the needle, and a spring platebetween which and the block, the needle passes, whereby it is retainedin the channel with the eye in line with the hole of the threading blockand means for holding the device elevated and in an inverted positionwhen not in use.

In witness whereof I have hereunto set my hand.

PATRICK BRALLEY.
